If there's a problem here, it's that large integers are being treated as floating-point numbers with insufficient precision to represent them properly. With the exception of Perl 6 (?!), programming languages all seem to agree that putting a period in a number gives them a license to return answers that don't agree with normal arithmetic. If you think about it, that's an odd thing to be unanimous about. Also, BigDecimal doesn't give "exact calculations" unless you stick to numbers with finite decimal expansions. BigDecimal can't do 1/3 without rounding.
